ADMINISTRATOR OF SAID FRANZ RAUCH- TOTALIZER-ENGAGING MECHANISM FOR CALCULATING MACHINES.

Application filed May 19,

T 0 all whom it may concern:

Be it known that FRANZ RAUCHWETTER, deceased, late a citizen of the German Republic, and residing at Berlin-Friedenau, Germany, has invented certain new and useful Improvements in Totalizer-Engaging Mechanism for Calculating Machines, of which the following is a specification.

This invention relates to calculating machines and more especially to adding machines which are provided with printing mechanism and refers to that class of such machines in which means are provided for printing at will (a) the items set on the keyboard, (1)) sub-totals (c) the grand totals.

A calculating machine of this type is shown and described in my pending United States patent-application Serial No. 17 1015, filed simultaneously with the present application, i. e. also on May 19, 1921.

TVith machines of this class it is necessary to provide means so that the gearing of the counter mechanism may be brought into and out of engagement with the differential mechanism, or in other words the counter may be lowered and raised at differing phases of the operation of the machine, according to whether it is desired to print (a) items set on the keyboard, (1)) sub-totals or (c) the grand totals. The means for effecting these changes have been brought into operation or set into position on the actuation of suitable keys provided for the purpose.

Various mechanisms have been used for causing the counter to be lowered and raised at the required times and it has been proposed in a machine for printing sub-totals and grand totals to provide a controlling device comprising two segments positively connected with the operating mechanism which by means of asystem of levers bring the counting mechanism into the necessary positions at the required phases of the operation of the machine. 7

It has also been proposed to employ a pair of cams controlling a pair of slides co-operating with a counter supporting plate.

1 According to my invention, I provide a cam disc upon which the counter rests, the said disc being operated by two sliding rods,

1921. Serial No. 471,013.

such rods being formed at their ends in engagement with the cam disc, with right angled slots, so disposed that when the horizontal portions of such slots pass over the pin connecting them to the cam disc, such cam disc is not moved but is only moved when one or other of such horizontal portions has passed or is prevented from passing over the pin, the sliding rods being actuated through lever and other mechanism by suitably disposed cams driven from the operating handle of the machine.

If a number is to be printed from the keyboard the raising and lowering of the counting mechanism is effected from the cam disc in such a manner that when the operating handle has been moved forward into the extreme position the counting mechanism is lowered into gear with the dilferentially set toothed segments at the same time the number set upon the keyboard is printed. Upon moving back the operating handle the gearing of the counting mechanism is operate: according to the movements of the dilferelr tially set toothed segments and at the end of the backward travel of the operating handle the counting mechanism is raised.

It, on the other hand a sub-total shown in the counting mechanism is to be printed, the lowering of the counting mechanism takes place immediately the operating handle begins to move forward, the keyboard at the same time being disconnected by a special mechanism. During the further movement of the operating handle the toothed segments move back until the discs of the counting mechanism show zero stops, which have been set in position. At the end of this movement of the toothed segments printing takes place, the impression taken representing the number in the counting mechanism, because the counting mechanism limits the movement of the toothed segments. hen the backwards movement of the operating handle commences, the toothed segments move the number of discs back again to the original numbers, and at the end of this movement of the operating handle the counting mechanism is lifted out of gear with the toothed segments so that in the counting mechanism the sub-total shown which has been printed is left unaltered.

For printing the grand total, the cam disc upon which. the counting mechanism is supported, is swung over immediately the operating handle starts to move. Thereby the, conntingmechanism is lowered and durng the continued nll re ent the oot d. segments are moved so far over that th counting mechanism shows zero. However when the operating handle starts to move back, the camdisc carrying the counting ing. and: loweringgear for-[the counting.

In the normal position of the cam disc 1 i. e. in the raised position of; thecounting mechanism, the slots 6 and 7 of the slide rods 8 and 9 are placed symmetrically in such a manner that the vertical parts of the slots come directly over the pivot 5.

This-means: that thescountingmechanism. is!

with. its cam surfaced? isturned in. thesa-me direction whereby theleuer lQ.isturned back into its. initial. position. As. the. lever 12 isconnectedwitlnthe;thrust bar- 9, this latter.

is shifted correspondingly andz thehorizom.

talwpart o-f'the angularslot of thisbar. moves freely awayover the-pivot 5.without taking this latter-along with it, that. is to say, withoutturningthe cam disk 1: so that. the parts and? 60' remain supported by this cam-v dislc Whenthen the-crank is. still further rotated, the cam surface 16 (of the cam 1%) which is located at an angle of 45 relatively to the cam-surface'17 contacts with the lower part of the lever 11 so that also this lever is swung back into its initial position and pulls the thrust bar 8 along with it. As the slot 6 of this bar contacts at its rear flank with the pivot 5 of the cam disk 1 (Fig. 6) also this pivot is taken along by the bar 8 and the cam-disk 1 is turned back into its initial position whereby the counting mechanism is raised.

During this cycle of movement the following operations have taken place (1) Printing the items set upon the keyboard at the end of the differential setting of the toothed segments of the keyboard mechanism.

(2) Adding the numbers set on to the counter during the return movement of the operating handle i. e. during the movement of the toothed segments back to their starting position.

(8) The raising of the counting mechanism after the addition'of the number has taken place.

(II). Control of the counting mechanism for printing Subtotals.

In order to print sub-totals it is first of all necessary as has been stated to disconnect the keyboard so that the differential toothed segments will not be influenced from the keyboard but only from the numbered discs of the counting mechanism 21, Fig. 1 is a lever which is operated in order to cause the printing keys to be set from the counting mechanism, this lever being arranged so that it may be rocked over by means of the sliding rod 22.

By the bar 22 also the lever 27 is raised by the intermediary of the members 23 and 2st, and the further actuation of the bar 22 may be effected in known manner, or by known means respectively (not shown), for instance by the so-called sub-total key. The lever 27 or rod swings on the pivot 25 which is guided in a longitudinal slot of the frame of the calculating machine. Lifting the lever or rod 27 is effected by means of the bell-crank lever 23 which is mounted on the pivot 23, and by means of the link rod 24, whereby the rod 27 cannot participate in the swinging movement of the lever 11 caused by the lifting disc 1st.

This bar 27 is however the auxiliary bar through which the locking or catch bar for the depressed key is operated which serves for controlling the stops for the toothed segments corresponding to the number value of the keys pressed down.

If therefore the rod or bar 27 is lifted (Fig. 2) by the mechanism just described so that it no longer participates in the reciprocating movement of the swinging lever 11 the stops for the toothed differential segments can be no longer set by pressing down a key on the keyboard, so that these segments first of all travel through the entire angular distance possible to them i. e. to the angular distance corresponding to the number 9.

It will thus be seen that this lifting of the rod 27 locks the keyboard and now the toothed segments may be operated from the counting mechanism until the number discs of the counting mechanism have been brought back to zero from the number previously set (the sub-total) this being effected by special zero stops as will be explained below.

The control of the counting mechanism must be effected in such a manner that, when the operating handle starts to move, it is first lowered, and during the further movement of the operating handle it is turned by the toothed segments up to the zero stops, at the same time setting into position and operating the printing types. During the return movement of the operating handle the nmnber discs of the counting mechanism are returned again into their original position; and the final movement of the operating handle lifts the counting mechanism.

This is effected in the following manner The lever 21 which was swung over from the sub-total key (Fig. 2) presses with the projection or tooth 28 upon the arm 29 of the slide rod 8 swinging on the lever 11, so that the slide rod 8 which is normally held up by the tension spring 30, is depressed for such a distance that the upper edges of the vertical part of the slot 6 come against the pin 5 of the cam disc 1, the pin 5 thereby being caught in the vertical part of the slot 6. The consequence is that, during the sliding movement of the rod or link 8, initiated by the lever 11 in the direction of the arrow 4, the pin 5 and thereby the cam disc 1 are carried along at once, the counting mechanism being lowered immediately into gear with the toothed segments, so that when the operating handle is pulled over, the gearing of the counting mechanism is at once engaged by the differential toothed segments and the numbered discs of the counter are turned from the numbers set to zero i. e. to the zero stops, as will be described hereafter.

The printing types which are coupled to the toothed segments are moved by a like amount, thus effecting the. printing of the sub-total.

After the impression of the sub-total has been made, the counting mechanism must be adjusted again so as to show the sub-total; it must therefore remain lowered when the operating handle starts to move back. \Vhereas the slide rod 8 has taken the cam disc 1 along at once, the slide rod 9 driven from the lever 12 slides with the horizontal part lOiS of the slot 'Tloosely over the :pin o fi the cam disc liasshown in Fig; 3. .The. slide rod 8 remains pressed down (Figs; 2 and. 3-) until the lever-29 hasipassed. t1-iearnr28ot the lever .21. Inorderto make more clear how thearm 29 can pass the arm..28 if the top of the cam 16 is in circumferentialline with the axis as a centre, I; point out what follows: The bar 8: is hinged tothe lever 11 by.means oi a pivot 8? (Figs. 1-4). If, in the position shown in Fig. 1., the lever 11 is depressedpby' the bar 22,. thebar -8 will be. caused to swing downwards on said pivot. 8 so asto. assume the position shown inFig. 2. then then the operatingcrank of the calculating machine is rotated, viz, from the position shownin. Fig. 2 intogithat shownv in Fig. 3, the-depressedbar8,..the verticalpart of the slot ofwhich surrounds the pivot 5, will turnthe cam-disk. 1 first into. the position shown. in Fig. 3'. and then into the position. shown in Fig. 4G,. and in that moment in which the pawl .29: has moved, with itsupper frontal surface,.past the. rear. edge of; the nose 28' the bar will, under the pull of the spring 20, turn. again upwards on itspivot' at'the lever 11 so that the pivot is-now located. in the horizontal part of the slot 6 (Fig. 41) lVhen the parts in question have arrived in this position, the bar 8. can be;movedrearwairds when the lever 11 is turned in rearward direction, that isto say, into. its. initial .posi: tion, as the pawl which.- is .retained by. the nose 28 can giveway to the left and can pass along, below said nose, thespring bein correspondinglyexpanded.

Aiiter having passed thisalever (Fig; 4.) the-arm 29.jun1ps upagain. under the in.- fluence of the spring 30, the slide. rod. there? byassumingitsnormalposition. Fig. etherefore represents that position of. the-inechanism inwhichbothislide rods-8 and-9 have completed their rearward travel, thisrposie tion being; opposite, .apartl-rom the posh tion ct the-lever 21, to the position of. the mechanism. atthe endof the i or-Ward travel of the. slide rods 8 and9 according, to Fig. 1. In. the initial position of the: crank. the upper, projecting rim of the cam surface 16 contactsuwith anupper lug; of the lever 11-, so that. w-henthe crank is-turned-in proper direction this levenis'turned atone to the left. Duringthe furthermovement of the crank thecamsurface. 17 which is .located behind the other cami-surfaceb-y. (of the cam disk 15) contacts with the-corresponding lug of the lever 12 and. turns also this lever to the. left (Fig. 1).. hen then the crank. is t-urned in: the reverse-direction, i..e. rearwards, the cam-surface 17 ofthe cam-disk 15 movesto-the left, past? the uppen lug of the lever 12, without interfering therewith, and then the projecting lower edge-of the cam-surface 17 contacts with ineees .moved forward bythe cam. disc 1 1i and the cam 16; the slide rod- 8- bymeans. of. the back edge 6 resting against thepin- 5- takes the cam disc 1 forward. i. erthe counting mechanism is lifted out of gear with the toothed segments into itsupper position. In order that the-discs of the counting-mechanism may be moved bacl'; from the numbers of the subetotal. into the cipher posit-ion: special zero stops or catches are provided (Figs? and 8), Fig. 7 shows the position ot'this ze-ro stop mechanism in its normal released l position whilst Fig. 8 shows it in: theone gaged position.

For every number 'disc this mechanism consists of a tooth or catch 3l'provided at the side: on the number disc, and-a rest or catch 32 which, may belowered into the path of this tooth or catch or lifted away from. it.

To effect this the catchi32 is mounted upon V afiap-34twhich can swing about thefpikvot 33; and is'held downby aspring 35 so that normally thecatch 32 issituateroutsidethe pathof the. tooth or catch 31 i. e: the numberv disc may be turned independent of the catch32 Ifit is desired, in order to print a sub or grand total, to bringthe catchi3'2- into the; path ofthe tooth or catclr 31- this: may be done:by'-me'ansof1 a specialmechanism, like wise: controlled-by the. suhor grand total key. vThismechanism; (.Fig. 7); consists of allover/36. swinging: on the: same pivot. 23 as the lever 23 and being coupled to this latter lever. The lever 36: is provided-with a link rod .37: tDwWhlOh' bell crankz-leven38 is con.- nect'ed soathat by the movement ofthe lever 86, .in the direction: of? the-arrow 89' the lever 38 is swung over. and'itslower air-11140 is raised into the position shown atFig. 8.. Fromthe counting' mechanism (which: can: be raised and lowered) a. rail 4-8 is suspended freely by the slots 41 and-rpins 42, thezupper front edge of'this rail being situated below the hinged? flap 1 3.4.

If the. counting mechanism is lowered while: the: subtotal or grand total key is pressed down.- i.. e; wliilethe: arm 40 of. the lever 38 is raised,. theerailaeflcannot drop down as well butremainsin itsiupper position,.whcreby the flap- 3%, which: isLhinge-d to the frame-of the counting mechanism at 33' is lowered. and swung up-witlrrcspect to the counter. Thereby the catch 32 is moved into the path of the tooth or the catch 51 and consequently the number disc of the counting mechanism can only turn until the teeth 31 come against the catches 32, the teeth 31 are attached to the number discs in the position corresponding to the ciphers.

In the extreme position the lever 38 must be securely locked, and must remain so whilst the impression of the numbers is made. For this reason a special locking arrangement has been provided for this position ofthe lever 38 and the slide rod 37 respectively. This consists (Fig. 7) of a bell crank 44. hinged to the slide rod 37 the arm as of the bell crank being provided with a roller 16. In the normal position of the slide rod 37 this roller 46 is outside the path of a flange at? of a segment l8 mounted upon the driving shaft 13. In the locking position of the slide rod 3'? and the lever 38 re spectively (Fig. 8) the'lever lat is swung over in such a way that the roller 4:6 comes in the path of the lower side of the flange 47. It therefore. remains locked to the driving shaft whilst the segment 38 is swung over, looking thus being assured. At the same time the segment 48 may also be used as a safe guard against accidental shifting of the slide rod 3. if the sub-total and grand total keys have not been pressed down, this being effected by the outer edge of the flange 47 being so dimensioned that in the normal position of the slide rod 37 it can move freely below the roller 46, thereby preventing an unintentional movement of the lever 44. This arrangement renders it impossible to press down the sub or grand total keys during the turning of the operating handle.

( III). 007M1 0f the counting awe/zanism during the printing of the grand total.

For printing the grand total the movements of the mechanism regarding the locking of the keyboard and the setting of the zero stops for the number discs are repeated in an identical manner to that described with regard to the sub-totals.

The lowering of the counting mechanism is the same i. e. the counting mechanism is lowered immediately the operating handle starts to move and consequently during the further movement of the operating handle the counter shows zero: the printing types being operated corresponding to this zero position. During the return movement of the operating handle however the counter is at once raised out of engagement. This is effected by the mechanism used for the raising and lowering of the sub-total printing gear, the mechanism-being merely supplemented by a few auxiliary levers, as represented in the special positions shown in Figs. and 6. A rod 21 is moved from the grand total key (Fig. ,1) this rod being located alongside the rod 22 and moving in a direction of the arrow -19 of the Fig. 1.

This rod is provided with a lateral projection 50 which in the direction of the movement comes in front of a stop 51 of the rail 22. If during the operation of the grand total key the rod 22 is moved it takes the rod 22 along with it, whereas during the operation of the sub-total key the rod 22 is moved alone i. e. rod 22 is not taken along. The rod 22 is pivoted to the lever 21 placed alongside the lever 21. Therefore when the grand total key is operated the levers 21 and 21 are swung over sii'nultaneously by the rods 22, 22 as shown in Fig. 5. As a result of this the sliding rod 8 is first lowered in the same manner as for the printing of the sub-total. The slide rod 9 cannot be lowered as its projection or tooth 52 rests upon the supporting lever 53. W hen the slide rods 8 and 9 are moved in the direction of the arrow, the arm 28 of the lever 21 presses upon the trip lever 56 fastened to the slide rod 9 in such a manner that it can turn under the influence of a spring on the trunnion 5 1, and presses it downward, without however the slide rod 9 being lowered because it is locked by the lever lVhen however, during the further sliding movement of the rod 9, the tooth 52 has passed the front face of the lever 53 as shown in Fig. 6, the slide rod 9 is lowered, with the result that the pin 5 of the cam disc 1 is caught in the vertical part of the slot 7 of the slide rod 9. During the return movement of the slide rod 9 (at the beginning of the movement rearward of the operating handle) the cam disc 1 is carried along at once i. e. the counting mechanism is lifted out of engagement with the toothed segments and for this reason the number discs remain at zero, the toothed segments are now moved back again into their normal position during the further return movement of the operating handle.
